The current sale price would be $123.60.
20% of $618 is 123.6. So turn that into dollars and cents and you get $123.60

-17 and 17
Answer:
x+5 is the factor..
Step-by-step explanation:
xsquare + (8+5)x + 40
or, xsquare +8x+5x+40
or, x(x+8)+5(x+8)
(x+5)(x+8)
Answer: 1080 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
Determine the values of b1, b2, and b3, the sides of the triangular base. Also determine the value of h, the height of the triangular base and l, the length of the prism (the length between the bases).
The sides of the triangular base are:
b1 = 13 in.
b2 = 14 in.
b3 = 15 in.
The triangular base is a right triangle, and so the height is one of our sides. We will use
h = 12 in.
The length of the prism is
l = 20 in.
total surface area = bh + (b1+b2+b3)*l
bh = 12*20 = 240 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
l * (b1+b2+b3) = 20*(13 + 14+ 15) = 840 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
TSA = bh + l * (b1 + b2 + b3) = 240 + 840 = 1080 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)

Answer:
The relation between x and y is
![y=\frac13 x^2](https://tex.z-dn.net/?f=y%3D%5Cfrac13%20x%5E2)
Step-by-step explanation:
Given that,
The value of y varies directly as the square of x.
![y\propto x^2](https://tex.z-dn.net/?f=y%5Cpropto%20x%5E2)
![\Rightarrow y=rx^2](https://tex.z-dn.net/?f=%5CRightarrow%20y%3Drx%5E2)
where r is constant of proportional.
Given that,
y= 27 and x=9
Plug y= 27 and x=9 in above relation
![y=rx^2](https://tex.z-dn.net/?f=y%3Drx%5E2)
![\therefore 27=r(9)^2](https://tex.z-dn.net/?f=%5Ctherefore%2027%3Dr%289%29%5E2)
![\Rightarrow 27 = r.81](https://tex.z-dn.net/?f=%5CRightarrow%2027%20%3D%20r.81)
![\Rightarrow r=\frac{27}{81}](https://tex.z-dn.net/?f=%5CRightarrow%20r%3D%5Cfrac%7B27%7D%7B81%7D)
![\Rightarrow r=\frac{1}{3}](https://tex.z-dn.net/?f=%5CRightarrow%20r%3D%5Cfrac%7B1%7D%7B3%7D)
The relation between x and y is
![y=\frac13 x^2](https://tex.z-dn.net/?f=y%3D%5Cfrac13%20x%5E2)
